According to one embodiment of the invention, single strip electrode 210 is made of several sub-electrodes 212, and each sub-electrode 212 that This is electrically insulated, six sub-electrode 212a~212f as shown in this figure.

Each sub-electrode 212 all includes sub-electrode unit 216.By taking sub-electrode 212e as an example, by three sub-electrode lists D1 is electrically connected first 216a~216c along a first direction.Sub-electrode unit 216a~216c connection types can be used transparent Or opaque conducting wire connection, conducting wire can be used transparent conductive material identical with sub-electrode unit 216a~216c, can also adopt Include copper, molybdenum, aluminium etc. with metal.In addition, each sub-electrode 212 is all provided with cabling 218, wherein sub-electrode 212 is by walking Line 218 is connected to controller (not being painted).

Multiple position units 214 are defined on substrate 202, each position units 214, which represent the touch panel, to be reached The minimum induction unit arrived, all position units 214 can collectively constitute the Touch Zone of touch panel 200 with array arrangement mode Domain.

Each position units 214 are defined by two sub- electrode units 216.And more importantly, each position units 214 are contained Lid or 216 type of corresponding two sub- electrode units and combinations thereof difference, are by belonging to the son in different sub-electrodes 212 respectively Electrode unit 216 is arranged in a combination, the details of this part will below with three different locations unit 214a shown in figure, It is explained for 214b, 214c.

It please notes that since each position units 214 are defined by two sub- electrode units 216, that is, each position units There are two sub-electrode units 216 in 214 ranges.Therefore herein its " covering ", the meaning indicated is 214 range of position units Sub-electrode unit 216 possessed by interior.

In position units 214a, position units 214a covers two different sub-electrode unit 216d and 216g, Wherein sub-electrode unit 216d belongs to sub-electrode 212b and sub-electrode unit 216g belongs to sub-electrode 212a.

In position units 214b, position units 214b covers two different sub-electrode unit 216e and 216h, Wherein sub-electrode unit 216e belongs to sub-electrode 212b and sub-electrode unit 216h belongs to sub-electrode 212c.

In position units 214c, position units 214c covers two different sub-electrode unit 216f and 216i, Wherein sub-electrode unit 216f belongs to sub-electrode 212c and sub-electrode unit 216i belongs to sub-electrode 212a.

In addition to this, in position units 214, the sub-electrode unit 216 covered respectively is to be arranged along second direction D2 Row, wherein second direction D2 is vertical with first direction D1.

According to one embodiment of the invention, each sub-electrode unit 216 have three it is parallel to each other along first direction D1 and The electrode pattern of electric connection, and there is opening between any two of which electrode pattern, as shown in Fig. 2, each sub-electrode unit 216 be similar comb shape.And in each position units 214, the two sub- electrode units 216 covered are respectively with electrode Pattern is mutually placed in corresponding opening.For example, by taking position units 214a as an example, the electrode pattern of sub-electrode unit 216d is located at In the opening of sub-electrode unit 216g, and the electrode pattern of sub-electrode unit 216g is located in the opening of sub-electrode unit 216d. Therefore, the area of position units 214a be equal to its corresponding to sub-electrode unit 216d and 216h area summation.

Through this configuration, mutual capacitance (coupled capacitor) can be generated with larger area between sub-electrode unit 216, also therefore touch-control Panel 200 has preferable sensitivity.It should be appreciated, however, that the electrode pattern of sub-electrode unit 216 provided above only for Show, rather than to limit the present invention, persond having ordinary knowledge in the technical field of the present invention can be according to actual needs, elasticity choosing Select the electrode pattern shape of sub-electrode unit 216.Such as the present embodiment is rectangle, is alternatively triangle or other geometric graphs Case.

In the present invention, because the sub-electrode unit 216 in sub-electrode 212 corresponding to each position unit 214 combines difference, So design can assign 214 uniqueness of each position unit and unique identity namely each position unit 214 are uniquely corresponding different The combination of sub-electrode unit in sub-electrode, to reach the effect of judging touch position.About the work(for reaching judgement touch position Effect, explains below in conjunction with diagram.

Fig. 3 A are please referred to, Fig. 3 A are the upper schematic diagram that one embodiment of position of touch is judged according to touch panel of the present invention. For example, in implementation, as user's finger or the touching of other touch objects or the position units 214c on substrate When, the electric signal (such as voltage caused by mutual capacitance or electric current) at position units 214c can change.Due to position units 214c covers the sub-electrode unit 216i of the sub-electrode unit 216f and sub-electrode 212a of sub-electrode 212c, so electric signal Change can cause the scanning between sub-electrode 212a and 212c output sensing signal generate change.

And for another aspect, other sub-electrodes 212 output sensing signal will not then be affected, in other words its The change of generation very little compared with change caused by sensing signal between sub-electrode 212a and 212c, and sub-electrode 212a and The category combinations of 212c only correspond to only one position units 214c.So the sense that system can be exported from specific sub-electrode 212 Signal is surveyed to be changed or judge touch position by definition knots modification size.

In Fig. 3 A, when system synchronization input drive signal is to sub-electrode 212a, that is, using sub-electrode 212a as defeated Enter end (Tx), then scan sub-electrode 212c and 212e respectively, that is, using sub-electrode 212c and 212e as receiving terminal (Rx). If the sensing signal for detecting the output of two of which sub-electrode 212 is changed, this represents the position corresponding to touch position Setting unit 214 is occurred at the same time and just in this two possessed two sub- electrode units 216 of the difference of sub-electrodes 212.

Fig. 3 B are looked at, wherein Fig. 3 B are to judge the upper depending on showing of another embodiment of position of touch according to touch panel of the present invention It is intended to.With aforementioned detecting mode, however in the present embodiment, sub-electrode 212b, 212d and 212f can be used as input terminal (Tx), And sub-electrode 212c and 212e can be used as receiving terminal (Rx), and input signal and scanning are carried out, to carry out touch position Detecting.On the contrary, can also using sub-electrode 212c and 212e as input terminal (Tx), and sub-electrode 212b, 212d and 212f is as receiving terminal (Rx) to carry out the detecting of touch position.

So with the touching decision mechanism of aforementioned present invention, as long as each position unit 214 covers corresponding sub-electrode list The permutation and combination of first 216 types is different, and system can judge that touching is to occur from the change of 212 sensing signal of each sub-electrode In which position units 214.

Fig. 2 is gone back to, by taking single electrode shown in Fig. 2 210 is made of six sub-electrode 212a~212f as an example, sub-electrode 212 form is broadly divided into three kinds.The first is sub-electrode 212a:The sub-electrode unit 216 of sub-electrode 212a has arrangement Rule, that is, the sub-electrode unit 216 of sub-electrode 212a is using two position units 214 as arrangement period.Second is son electricity Pole 212b and 212f:Sub-electrode 212b and 212f are located at first place (most left in figure) and the last position (in figure of electrode 210 It is most right) and there are two sub- electrode units 216.The third is sub-electrode 212c~212e:Sub-electrode 212c~212e has respectively There are three sub-electrode units 216.

Such as because invention demand therefore so that electrode 210 need use more position units 214, then increase composition electrode 210 third seed electrode 212 (212c~212e in Fig. 2) will can increase the quantity of permutation and combination.Relatively, the first seed Electrode 212 (212a in Fig. 2) also 210 extension of counter electrode, and still maintain aligned identical regular.And the first and last position Still it is set as second seed electrode 212 (212b and 212f in such as Fig. 2).

In addition to this, the touch panel 200 of the present invention utilizes the arrangement group of the sub-electrode unit 216 of different sub-electrodes 212 Conjunction mode is needed individually to pick out cabling and is connected to control with corresponding touching each position unit 214 with each touch position unit The mode of device is compared, and the touch panel 200 of the present invention can reduce 218 quantity of cabling being connect with controller, draw so as to reduce The area for the neighboring area that line occupies, is conducive to the design of touch panel narrow frame.

In the present embodiment, touch panel 200 adopts unilateral outlet, that is, the cabling 218 of sub-electrode 212 all goes out in the same direction Figure is shown as illustrating by line below however, the touch panel 200 of the present invention can also adopt bilateral outlet method.

Fig. 4 is please referred to, Fig. 4 is the upper schematic diagram according to another embodiment of touch panel of the present invention.The touch-control of the present invention Panel 200 includes substrate 202 and electrode 210, multiple position units 214 has wherein been defined on substrate 202, and a plurality of electric each other Property insulation electrode 210 be set on substrate 202.

D1 extends electrode 210 along a first direction, and is arranged in parallel with each other.Single strip electrode 210 is by several sub-electrodes 212 It is constituted, each sub-electrode 212 is electrically insulated from.

Each sub-electrode 212 all includes sub-electrode unit 216 and cabling 218, the cabling of which part sub-electrode 212 218 along a direction outlet, and the outlet in another direction of cabling 218 of another part sub-electrode 212.By taking this figure as an example, sub-electrode 212 cabling 218 is respectively toward 202 both sides outlet of substrate.

Each position units 214 are defined by two sub- electrode units 216, and as described above, each position units 214 are covered Or corresponding 216 type of sub-electrode unit and combinations thereof difference, it is by belonging to the sub-electrode list in different sub-electrodes 212 respectively Member 216 is composed.

In the present embodiment, because the son in same strip electrode 210 in 214 corresponding sub-electrode 212 of each position unit is electric The permutation and combination of pole unit 216 is still different, therefore each position unit 214 can still maintain unique, unique identity namely each position Unit 214 uniquely corresponds to the combination of the sub-electrode unit 216 in a kind of different sub-electrode 212, to reach judgement touch position Effect.And the permutation and combination and each position list of the sub-electrode unit 216 in sub-electrode 212 are corresponded to about each position unit 214 The touch detection mode of member 214 has been specified in previous embodiment, and details are not described herein.

In Fig. 4, single electrode 210 is made of eight sub-electrodes 212, and wherein the form of sub-electrode 212 can substantially divide It is four kinds.The first is sub-electrode 212a:The sub-electrode unit 216 of sub-electrode 212a has queueing discipline, that is, sub-electrode The sub-electrode unit 216 of 212a is using two position units 214 as arrangement period.Second is sub-electrode 212b and 212h: Sub-electrode 212b and 212h are located at the first place of electrode 210 and last position and have two sub- electrode units 216.The third For sub-electrode 212e:Sub-electrode 212e has three sub- electrode units 216, and is located substantially at the centre of electrode 210.4th kind is Sub-electrode 212c~212g:Sub-electrode 212c~212g be located between the first sub-electrode 212b and sub-electrode 212e and Between the sub-electrode 212h and sub-electrode 212e of last position, it is respectively provided with three sub- electrode units 216.

This figure is on the basis of the sub-electrode 212e among electrode 210, sub-electrode 212e and on the right side of sub-electrode 212e Sub-electrode 212, cabling 218 turns right outlet.On the contrary, the sub-electrode 212 on the left of sub-electrode 212e, cabling 218 toward left side outlet.Therefore, in the bilateral outlet of electrode 210,218 ratio of cabling of outlet and outlet to the left to the right Substantially 1:1.

It should be appreciated, however, that provided above is only illustration on the basis of sub-electrode 212e, rather than to limit this hair Bright, persond having ordinary knowledge in the technical field of the present invention can be according to actual needs, and elasticity is selected as the sub-electrode of benchmark 212, the bilateral outlet ratio or outlet direction of the cabling 218 of sub-electrode 212 is arranged.
